0973 Maternal Depression And Infant Sleep Duration Trajectory In The First 3 Years: A Prospective Cohort Study

Abstract Introduction The study was to investigate trajectories of infant sleep duration and associations with trajectories of maternal depression status during 3 years post-partum. Methods Data were from the Child Health Promotion Project in Shanghai (CHPPS). Mothers were recruited at the third trimester of pregnancy and followed up together with the infants until 36 months postpartum. Between 2012 and 2013, 262 women (Mage=29.5, SDage=3.2, range: 22-39 years old) were recruited and were followed from June 2012 to August 2015. Sleep duration of the children was assessed using Brief Infant Sleep Questionnaire (BISQ) at 42 days, 3 months, 6 months, 9 months, 12 months, 18 months, 24 months, and 36 months postpartum. Center for Epidemiological Survey-Depression Scale (CESD), Edinburgh Postnatal Depression Scale (EPDS), and the Profile of Mood States (POMS) were used to measure the mother’s depression status at late pregnancy, 42 days postpartum, and 12-36 months postpartum, respectively. The group-based trajectory models (GBTM) were used to estimate patterns of infant sleep duration development and maternal depression status. Results Two trajectories of infant day sleep duration were identified, defined as “initial short sleepers” (54.8%) and “initial long sleepers” (45.2%). Three trajectories of infant night sleep duration were identified, labeled as “increasing” (8.5%), “stable” (61.7%), and “mild declining” (29.8%). Two trajectories infant total sleep duration were identified, defined as “initial short sleepers” (51.5%) and “initial long sleepers” (48.5%). Two trajectories of maternal depression status were identified, labeled as “low” (74.2%) and “high” (25.8%). After controlling for covariates, women who have higher depression status had infants of shorter day sleep duration. There was no significant association with infant night sleep duration. Conclusion Our study suggests that maternal postpartum depression is associated with short infant day sleep duration, but not with infant night sleep duration.

Patterns of cross-correlation in time series: A case study of gait trails**Project supported by the National Natural Science Foundation of China (Grant Nos. 11805128, 11875042, 11505114, and 10975099), the Program for Professor of Special Appointment (Orientational Scholar) at Shanghai Institutions of Higher Learning, China (Grant Nos.

A complex system contains generally many elements that are networked by their couplings. The time series of output records of the system’s dynamical process is subsequently a cooperative result of the couplings. Discovering the coupling structure stored in the time series is an essential task in time series analysis. However, in the currently used methods for time series analysis the structural information is merged completely by the procedure of statistical average. We propose a concept called mode network to preserve the structural information. Firstly, a time series is decomposed into intrinsic mode functions and residue by means of the empirical mode decomposition solution. The mode functions are employed to represent the contributions from different elements of the system. Each mode function is regarded as a mono-variate time series. All the mode functions form a multivariate time series. Secondly, the co-occurrences between all the mode functions are then used to construct a threshold network (mode network) to display the coupling structure. This method is illustrated by investigating gait time series. It is found that a walk trial can be separated into three stages. In the beginning stage, the residue component dominates the series, which is replaced by the mode function numbered M14 with peaks covering ∼680 strides (∼12 min) in the second stage. In the final stage more and more mode functions join into the backbone. The changes of coupling structure are mainly induced by the co-occurrent strengths of the mode functions numbered as M11, M12, M13, and M14, with peaks covering 200–700 strides. Hence, the mode network can display the rich and dynamical patterns of the coupling structure. This approach can be extended to investigate other complex systems such as the oil price and the stock market price series.

The development of bronchoscopy in China: a national cross-sectional study.

Objective: To investigate the development of bronchoscopy in China and compare it with its application in the early 21st century.Methods: The data collection was based on questionnaires. Three hundred and nineteen hospitals, which distributed across 30 provinces and 130 cities, were included in the study. Data about the application of bronchoscopy in Shanghai and Hunan province in the early 21st century are also involved for comparison.Results: The median period of performing diagnostic and therapeutic bronchoscopy was 19.7±11.0 and 7.4±7.0 years, respectively. On average, about 155.2 cases and 28.4 cases received diagnostic and therapeutic bronchoscopy in each hospital per month. The average area and number of the examination room was 122.7m2 and 2.2m2, respectively. More examination items were performed in specialty hospitals than those in general hospitals (P<0.05) and specialty hospitals owned more rooms exclusively for bronchoscopy (P<0.05), while no difference of the number of allocated doctors was found (P>0.05). On the other side, the whole amount of diagnosis and therapeutic items in teaching hospitals was slightly higher than that in non-teaching hospitals (P<0.01). Comparison of diagnosis and therapeutic endoscopy in Shanghai and Hunan province shows that the number of flexible bronchoscopy increased by 5.8 times in Shanghai from 2002 to 2017, while that increased by 3.4 times in Hunan province from 2005 to 2017. Furthermore, the average number of allocated doctors increased by 0.85 times in Shanghai, which was more rapidly compared with that of Hunan province (0.66 times) (P<0.05). Besides, the development rate of the diagnosis and therapeutic projects in Shanghai was significantly higher than that in Hunan province (P<0.05).Conclusion: All different classes of hospitals in China are capable of carrying out conventional bronchoscopy diagnosis and therapeutic projects, and newly developed bronchoscopy technology has gradually spread in high-level hospitals since 21st century. The higher class the hospital was, the earlier bronchoscopy was performed. Respiratory endoscopy in China has developed rapidly since the early 21st century and the construction of respiratory endoscopy center and the personnel training are on the right track, but it is also faced with inadequate equipment, unbalanced regional development and insufficient personnel allocation.

Reclamation pathway of waste piles: A case study in Shanghai

Reclaiming waste driven piles to use as the foundations of new buildings is an innovative and effective approach to manage waste driven piles for cleaner construction. A reclamation pathway for waste driven piles is proposed based on a renewal project in Shanghai. A detailed evaluation of the durability and bearing capacity of the waste driven piles is performed. Post-construction settlement in a normal building and a building with a foundation constructed with a combination of new and waste piles is compared to evaluate the performance of the waste piles. Technical suggestions are summarized to improve the reclamation pathway based on the findings of the renewal project. The results show that both the durability and bearing capacity of the waste piles meet the requirements of engineering applications. Reuse of waste piles reduced average settlement but increased the uneven settlement of the new buildings. Economic analysis indicates that reuse of waste driven piles in foundations of new buildings can save approximately $573,672 in construction costs and 1017.6 m3 in concrete for a project the size of the renewal project. Both technical and economic assessments corroborate the reclamation pathway for waste driven pile is necessary and appropriate for Shanghai. The proposed reclamation pathway benefits the management of waste piles and facilitates the cleaner production of construction industry.

The Rules in Reconnecting the City Fabrics: A Morphological Study of the Regeneration Case

In the recent 30 years, Shanghai experienced fast urbanization which landscape shows various types of conflicts among the modern forms and the traditional forms. The insertion of new typologies in the traditional district introduces new urban characteristics and dynamics, which are not typically associated with the traditionally framed cities. The constructions of substantial industrial and commercial projects have caused the demolition of traditional urban forms. Urban designers aspire to revitalize the traditional neighborhood by combining urban fabrics without destroying the structure of the historic neighborhood. This paper attempts to exam the effectiveness of the urban network, the continuity of public structures and operational interactions between new projects and the local context through the study of a “failed” regeneration project in Shanghai, China. Consequently, this paper raised rules in reconnecting the city fabrics towards differential urbanism.

Collaborative Public Space in China: Two Waterfront Projects, Shanghai and Suzhou

This paper discusses public space in China and explores how theories of public space can be applied to two waterfront projects. As case studies the paper compares two public waterfront projects: The 18 km Jinji Lake project in Suzhou and the 45km Huangpu River waterfront project in Shanghai, both completed in 2018. The Jinji lake development in the heart of Suzhou designed by EDAW later AECOM also boasts inclusive 24/7 access and people centered design. Democratic theory is commonly used in the West to discuss public space however LiminHeearguesthatthediscourseasunderstoodinthewesterndemocratictradition is not adequate for Asian cities (Hee, 2017). Constructing Singapore Public Space, Springer) This paper finds that although the idea of public space in China is argued to be an evolving concpt (Gaubatz, 2008, pp 72-83), notions of democratic participation, Human Centered Design (HCD) and place-making methods are central development policyinChinesecities.Whereastermslikevibrancyandvitalityarecommonlyusedby scholars to evaluate and discuss public space in China, rather than democratic theory, theories from western scholars such as Habermas’s theory of the public sphere are also relevant and collaborative practices between civil society and the state are key to the participatory nature of Chinese public space.

Suppressing risk propagation in R&D networks: the role of government intervention

PurposeThis paper aims to explore what factors influence the possibility of internal and external risk propagation in R&D networks and investigate how government intervention moderates the associations between the influencing factors and risk propagation.Design/methodology/approachThe authors divided government intervention into directive and facilitative intervention and adopted an empirical research approach in this study. They collected 228 questionnaires from managers and R&D personnel participating in R&D projects in Shanghai and Jiangsu province through e-mail and in person. The data were used to carry out multiple regression analysis to test hypotheses.FindingsThe results show that the probability and consequence of risks positively affect the possibility of internal and external risk propagation; risk perception and transformation ability negatively influence the possibility of internal and external risk propagation; both directive and facilitative intervention weaken the relationship between the probability of risks and internal risk propagation when they are high than low the association between transformation ability and internal risk propagation is weaker when directive intervention is high than low, whereas facilitative intervention presents the insignificant moderation effect on the relationships between risk perception ability and internal and external risk propagation.Originality/valueThis study provides a distinctive theoretical perspective for risk conduction theory, government intervention theory and risk management. It also offered managers and the government a clear understanding of how to reduce or avoid risk propagation by leveraging directive and facilitative government intervention.

Application of the design code for steel fibre reinforced concrete into finite element software

Steel fibre reinforced concrete (SFRC) is more and more used as construction material. Well-known are applications for industrial floors. Nevertheless, this material is also widely used in structural concrete elements where it is especially effective to cover crack widths in combination with standard conventional reinforcement. Currently there is no general part in Eurocode 2 [1] for buildings regarding steel fibre concrete. There are various standards and recommendations for the calculation of the steel fibre contribution. One of the most applied publications is the German guideline DAfStb [2] which was used as a basis for the numerical analysis outlined in this paper. Thus, company SCIA N.V. together with Bekaert N.V. as producer of DRAMIX® fibres developed a special tool for designing and checking SFRC structures. This tool was built in into finite element software SCIA Engineer and based on the German guideline. To gain a fundamental understanding of the structural behaviour, we have also developed non-linear FEM models, which contain a built-in module for SFRC structures. Numerical simulation results are compared to experimental performance of SFRC slab on piles of the Nanhui project in Shanghai in terms of ultimate load and crack pattern.

In‐Situ Marginalisation: Social Impact of Chinese Mega‐Projects

AbstractThis study offers a detailed analysis of an under‐researched social problem of in‐situ marginalisation and its causes by drawing on the concept of state entrepreneurialism. Our empirical data stem from the Lingang mega project in Shanghai and one of its neighbourhoods named Neighbourhood No.57 where we find that the residents have not been relocated but are instead suffering from declining public services and environmental quality from surrounding industrial developments. The root cause of this problem is the municipal government’s prioritisation of its strategic objectives of economic development over the livelihood of local residents. The strategic vision of the municipality has led to mass relocation in its early phases of development but in its later stages leaves many residents waiting for relocation whilst being gradually surrounded by industrial developments. Despite continued residential complaints and petitions, in‐situ marginalisation is not resolved due to the institutional arrangement of Lingang, which has centralised planning and financing powers to newly created project‐oriented state organisation. Social responsibilities have been relegated to lower‐tiered governments in Lingang which have neither planning power nor the financial resources to resolve the problems of residents. By examining the case of Lingang, this paper provides a different analytical framework for explaining the social problems emerging from China’s mega urban developments.

Risk assessment of urban rooftop distributed PV in energy performance contracting (EPC) projects: An extended HFLTS-DEMATEL fuzzy synthetic evaluation analysis

Promoted by the policy, urban rooftop distributed photovoltaic (URDPV) has developed rapidly in China. Besides, the government is gradually applying energy performance contracting (EPC) mode to this field making use of urban rooftop resources and energy service companies’ (ECOs’) technological advantages, but there are still obstacles to further development. One of the main reasons that restrict the further development of EPC-URDPV projects in China is the lack of effective risk assessment method. This paper aims to identify the critical risk factors (CRFs) for such projects, and propose a comprehensive risk assessment framework. Firstly, 11 CRFs are identified based on the literature review and 4-dimensional risk analysis to composed the risk assessment index system. Secondly, the weights of CRFs are determined by the intuitionistic fuzzy-decision making trial and evaluation laboratory (IF-DEMATEL) method. It is worth noting that this paper uses the hesitant fuzzy linguistic term sets (HFLTS) to obtain evaluation information to ensure the completeness and fuzziness of experts’ viewpoints. Then, an extended HFLTS-DEMATEL fuzzy synthetic evaluation method is used to conduct risk assessment. The evaluation results show that the risk levels of EPC-URDPV projects in most study areas are at “Medium” and “Relatively Low” state. The risk level of projects in Shanghai and Fujian is “Relatively High”. Sensitivity analysis results show the stability and reliability of the model. After considering the causes of risk and relevant stakeholders, a risk response is proposed. This study can enrich the methods in the field of risk assessment and provide insightful references to PV investors, decision makers.

The Energy Performance Evaluation of Roof Retrofit Under Uncertainties for the Shanghai’s Worker Village

Retrofitting the building roof of the Shanghai Worker Village is one of the governmental projects in Shanghai to improve the city appearance and energy efficiency of existing buildings. The roof is one of the most important building components to determine the energy performance. Hence, how to appropriately select the roof insulation level is a key question to answer to achieve the optimal performance in the building retrofit. Using the building simulation tool such as EnergyPlus, engineers typically run the deterministic simulation to evaluate the effectiveness of different roof insulation levels in the practice. However, this approach could result in bias due to the insufficiency of the deterministic approach in dealing with the complexity in the building performance simulation. In this study, to better mimic the real scenarios of buildings especially for the urban-level retrofit project, we utilized the uncertainty analysis considering impacts of urban heat island effect, material and building operation uncertainties to conduct a thorough evaluation of possible roof insulation retrofit scenarios. The results indicate that as we further increase the insulation levels, the effectiveness of adding insulation on the heating and total HVAC load saving decease significantly. In the uncertainty analysis, there exists a high probability of overlap in terms of the load saving if sufficient amount of insulation is already attached to the roof. Also, considering the characteristics of the retrofit building and weather conditions, adding extra roof insulation alone might only result in limited impact on the overall energy saving of a building. A further lifecycle analysis is necessary to determine the most efficient way of adding insulation for the roof retrofit.

Responsive Structure: Architecture as a Thing‐scape

Structure should be not just a technical issue, but integral to architectural expression. As architect Yichun Liu argues here, the modern separation of architecture from structural engineering in both education and professional practice is impoverishing the built environment. The office that he co‐founded, Atelier Deshaus, has evolved a new model of design that involves close collaboration with engineers from the outset, to generate works that respond richly to their physical and cultural context. Four projects in Shanghai, where the firm is based, illustrate how it works.

Deep Shanghai project – A strategy of infrastructure integration for megacities

Urban Underground Infrastructures (UUI) are crucial for megacities that are suffering weak adaptabilities of environmental threats while facing fast economic growth from highly concentrated urban developments. Because of the urbanization and densification of cities globally, Metropolitan Authorities must prioritize the use of shallow and deep Urban Underground Space (UUS). Effective management of such space requires specifications of use for the varying levels within these. The specifications are defined as “Vertical zoning” (namely “Depth-scape”). This paper suggests a strategy for an economic development plan for Shanghai in China. Its specific focus is that of Deep Underground Space (DUS). The authors also suggest that this strategy may be transferable to other cities experiencing similar urbanization and densification, globally.In urban centers, surface buildings and facilities have been connected through shallow tunnel transport systems for pedestrian, utility, vehicle, metro, train, at a micro scale. For a larger urban territory, Special transport systems ensuring city’s security, resiliency and sustainability are usually built in the deep underground, such as: disaster evacuators, flood drainers (“sponge city creators”), terminal freight deliveries, waste movers, energy transmitters, cavern connecters and deep shaft elevators. A strategy proposed in this paper will incorporate these macro scale deep infrastructures into the economic development plan of Shanghai city. Methods applied in this paper include: Resources potential evaluation framework, Strategic benchmarking model, Conceptual infrastructure planning and Investment project appraisal scheme.Integration between municipal infrastructures and underground infrastructures is beneficial for the long-term operation of megacities, where utility systems and municipal facilities keep sizing up to meet future demand. Infrastructure integration becomes a must rather than an option. Developing Special Transport Systems in the Deep Underground Space (DUS) will allow a megacity to scale up its infrastructure stock, save surface land resources, protect societal assets, mitigate calamity losses, sustain operability and improve livability.

A Geodesign Method of Human-Energy-Water Interactive Systems for Urban Infrastructure Design: 10KM2 Near-Zero District Project in Shanghai

Abstract The grand challenges of climate change demand a new paradigm of urban design that takes the performance of urban systems into account, such as energy and water efficiency. Traditional urban design methods focus on the form-making process and lack performance dimensions. Geodesign is an emerging approach that emphasizes the links between systems thinking, digital technology, and geographic context. This paper presents the research results of the first phase of a larger research collaboration and proposes an extended geodesign method for a district-scale urban design to integrate systems of renewable energy production, energy consumption, and storm water management, as well as a measurement of human experiences in cities. The method incorporates geographic information system (GIS), parametric modeling techniques, and multidisciplinary design optimization (MDO) tools that enable collaborative design decision-making. The method is tested and refined in a test case with the objective of designing a near-zero-energy urban district. Our final method has three characteristics. ① Integrated geodesign and parametric design: It uses a parametric design approach to generate focal-scale district prototypes by means of a custom procedural algorithm, and applies geodesign to evaluate the performances of design proposals. ② A focus on design flow: It elaborates how to define problems, what information is selected, and what criteria are used in making design decisions. ③ Multi-objective optimization: The test case produces indicators from performance modeling and derives principles through a multi-objective computational experiment to inform how the design can be improved. This paper concludes with issues and next steps in modeling urban design and infrastructure systems based on MDO tools.

Low-carbon promises and realities: Lessons from three socio-technical experiments in Shanghai

Abstract China's ongoing transition to a modern urban-centered economy is accompanied by ambitions of sustained economic growth as well as promises of environmentally sustainable futures for its cities. In this paper we critically assess how these two ideas are combined and translated into realities on the ground by examining three low-carbon development projects in Shanghai: Anting New Town, Dongtan Eco-City, and Hongqiao CBD's low-carbon transportation hub. By mobilizing insights from the academic field of Sustainability Transitions – specifically on expectations, experimentation and innovation journeys – we show how the original plans derailed and why until now there has been limited success in living up to the promises of sustainability. To realize the promises more fully in future projects we identify three broad lessons for the actors involved: they should nurture a set of parallel pathways, foster a more experimentalist mindset, and learn to embrace uncertainty.

Engineering Application and In-situ Monitoring Analysis of Retaining Structures of New H-section Steel Support System in Foundation Pit

A new H-section steel support system is introduced based on a foundation pit project in Shanghai. In-situ monitoring was carried out to measure the displacement of supporting piles. The monitoring results showed that the displacement of pile-top was closely related to the excavation depth and time. It is basically no longer developing after the foundation slab concreted finished. Horizontal displacement of the pile body increased gradually with the increase of excavation depth. The maximum horizontal displacement was about 25 mm and the position was about 1 m below the bottom of the foundation pit. Finally, the horizontal displacement of the pile body was presented as a "bow" with a small displacement at two ends and a large displacement in the middle. Compared with those at reinforced concrete support area, it showed that the deformation law and final displacement value of pile-top and pile body in the new H-section steel support area was basically the same as that of reinforced concrete support area. And all of the monitoring data were within the security range, meeting the design and code requirements. Moreover, new H-section steel support system construction period was short and the cost was low. It could effectively improve the green construction level. The conclusions obtained in this paper could be referred for other familiar projects.

How the roofing morphology and housing form affect energy performance of Shanghai’s workers’ village in urban regeneration

Typologies of the building roof influence the form and the view of a city, and have an impact on its energy performance. “From Flat to Slope Roof” is a governmental project in Shanghai to renovate workers’ villages over the past two decades. The project aimed to change monotonous appearance of the urban roofscape by replacing the flat roof with the slop roof, and to bring benefits of passive cooling through the slide roof to reduce energy demand caused by excessive air-conditioning. However, how different roofing typologies affect the building energy performance requires further investigation. Previous test results have shown that near 6% reduction of total annual building energy consumption could be achieved with the substitution of the polymer material on flat roofs, compared with the reduction by 3% on walls, and the reduction by 2% on floors. In this paper, the numerical modeling with EnergyPlus was applied to test the variation of roofing types and how they would affect the total energy consumption from level of a building to the entire whole community. The results show a connection between the thermal insulation of roof morphology and building energy performance, which conclude an energy reduction strategy through urban design in a neighborhood scale.

A uniform framework of projection and community detection for one-mode network in bipartite networks**Project supported by the National Natural Science Foundation of China (Grant Nos. 11505114 and 10975099), the Program for Professor of Special Appointment (Orientational Scholar) at Shanghai Institutions of Higher Learning (Grant Nos. QD02015016 and DUSST02), the Shanghai Project for Construction of Discipline Peaks, the Natural Science Foundation

Projection is a widely used method in bipartite networks. However, each projection has a specific application scenario and differs in the forms of mapping for bipartite networks. In this paper, inspired by the network-based information exchange dynamics, we propose a uniform framework of projection. Subsequently, an information exchange rate projection based on the nature of community structures of a network (named IERCP) is designed to detect community structures of bipartite networks. Results from the synthetic and real-world networks show that the IERCP algorithm has higher performance compared with the other projection methods. It suggests that the IERCP may extract more information hidden in bipartite networks and minimize information loss.

The Choice and Reason Analysis of Measurement Model of Investment Real Estate in China

Pursuant to the provisions in Accounting Standard for Business Enterprises No. 3 - Investment Property (CAS3) issued on February 27, 2006 by the Ministry of Finance, China’s investment real estate follow-up measurement method can choose the cost model or the fair value model. But after investigation we found that, currently, only less than 5% of the enterprises with investment real estate projects in Shanghai and Shenzhen used a fair value model in the follow-up measurement. Therefore, in view of this phenomenon, this paper analyzes the factors influencing the fair value measurement model of investment real estate.
